Emmanuel, About 1st question sorry about my inexperience but I don´t know how to turn the CPU profiling in the JVM, can you tell me how to do it or where can I find info about it ?
About 2nd question our architecture is a Jboss HA architecture with 2 Front-Ends in cluster receiving request in a ejb-clients and 2 Jboss BE in cluster with ejb-beans in both BE that receive from client in FE request. This ejb-beans in BE make the request to sequoia in order to sincronize mysql database in both nodes. I hope now you can underestand our architecture. Thanks again, Toni. 2008/7/30, Emmanuel Cecchet <[EMAIL PROTECTED]>: > > Hi Toni, > > It would be interesting to know where Sequoia actually spends its time. > Could you turn the CPU profiling in the JVM to get an idea of what is going > on? > Also what does your configuration look like? > > Thanks for the feedback, > Emmanuel > >> We are doing some load test of on product using JBOSS, Sequoia and MySQL, >> and in our test we have notice that sequoia get a very big, big, big >> quantity of CPU... >> Look top in machine where the service is processes ( nearly 150%cpu ), we >> are talking about servers with 2 CPUS : >> >> top - 14:36:31 up 25 days, 22:28, 2 users, load average: 6.87, 6.53, >> 3.66 >> Tasks: 104 total, 1 running, 103 sleeping, 0 stopped, 0 zombie >> Cpu(s): 59.0% us, 8.1% sy, 0.0% ni, 29.6% id, 0.7% wa, 0.3% hi, 2.3% >> si >> Mem: 8164704k total, 5899548k used, 2265156k free, 387168k buffers >> Swap: 8385920k total, 0k used, 8385920k free, 3190788k cached >> >> PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND >> 26562 sequoia 17 >> 0 2010m 366m 14m S 150 4.6 16:28.59 java >> 5809 jboss 25 0 2049m 1.1g 73m S >> 89 14.7 11:55.62 java >> 21342 mysql 16 0 544m 371m 4872 S 37 4.7 43:01.14 >> mysqld >> And this in the BE which is not processing any traffic : >> >> top - 14:42:00 up 25 days, 22:33, 2 users, load average: 3.99, 4.57, >> 3.67 >> Tasks: 104 total, 1 running, 103 sleeping, 0 stopped, 0 zombie >> Cpu(s): 36.8% us, 5.2% sy, 0.0% ni, 54.9% id, 0.4% wa, 0.3% hi, 2.3% >> si >> Mem: 8164704k total, 5968124k used, 2196580k free, 387396k buffers >> Swap: 8385920k total, 0k used, 8385920k free, 3262028k cached >> >> PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND >> 26562 sequoia 17 >> 0 1966m 365m 14m S 141 4.6 22:42.70 java >> 21342 mysql 16 0 545m 371m 4872 S >> 35 4.7 44:32.83 mysqld >> > _______________________________________________ > Sequoia mailing list > [email protected] > https://forge.continuent.org/mailman/listinfo/sequoia >
